The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.

The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.

For detailed information about how seriation works, see Seriation: A Step by Step Description.

Seriation is thought to be the first application of statistics in archaeology. The most famous seriation study was probably Deetz and Dethlefsen's study Death's Head, Cherub, Urn and Willow, on changing styles on gravestones in New England cemeteries.

Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating.Like tail fins on a Cadillac, artifact styles and characteristics change over time, coming into fashion, then fading in popularity. The standard graphical result of seriation is a series of "battleship curves," which are horizontal bars representing percentages plotted on a vertical axis.Plotting several curves can allow the archaeologist to develop a relative chronology for an entire site or group of sites.Without those, the archaeologists were in the dark as to the age of various societies. The use of tree ring data to determine chronological dates, dendrochronology, was first developed in the American southwest by astronomer Andrew Ellicott Douglass.In 1901, Douglass began investigating tree ring growth as an indicator of solar cycles.
